Struct AnnotationArg 

pub struct AnnotationArg { /* private fields */ }

Implementations

impl AnnotationArg

pub fn name_token(&self) -> Option<SyntaxToken>

pub fn nested_args(&self) -> Option<AnnotationArgs>

The nested paren-clause (reads(gold, hp) inside effects(…)), if this argument has one.

pub fn path(&self) -> Option<Path>

The unquoted ::-separated module PATH (story::old::path), if this argument is one (issue #1349, @[was(story::old::path)]’s arg form). name_token is None for this shape — the arg’s direct child is a PATH node, not a bare IDENT token.

pub fn eq_value(&self) -> Option<StringLit>

The = "value" clause’s string-literal value (issue #1719, @[element(args = "…")] / @[style(chan = "…")]), if this argument has one. None for the bare-IDENT, nested-clause, path, and numeric-literal shapes — only the key/value form parses a STRING_LIT as a sibling of the key IDENT rather than the arg’s sole child.

pub fn eq_int_value(&self) -> Option<IntegerLit>

The = <integer> clause’s integer-literal value (issue #2164, @[convention(…, order = 30)] — the ordering key is a bare integer, RULED). None for every other clause shape, including the string key/value form Self::eq_value reads — a clause carries at most one of the two, never both.

pub fn eq_ident_value(&self) -> Option<SyntaxToken>

The = <ident> clause’s bare-identifier value (issue #2178, @[convention(…, attach = Cue)] — the attached schema names a declared struct, so this clause is a bare identifier, not a quoted string or integer literal). None for every other clause shape.

Unlike Self::eq_value/Self::eq_int_value, this is not a distinct child node kind — the value is bumped as a second bare IDENT token, a sibling of the key’s own IDENT token (see parser::annotation::annotation_arg’s IDENT arm). So this reads the second direct-child IDENT token, not the first (which Self::name_token already owns).
